Filtrete 12x12x1 Air Filter, MPR 1500, MERV 12, Healthy Living Ultra-Allergen 3-Month Pleated 1-Inch Air Filters, 4 Filters

When I was ordering, I needed 20X25X1 ---that is what I had searched for and that is what I clicked on. Since I needed 4 of them, I selected a 4 pack. What I didnt realize was that when I clicked on 4 pack, the size changed and when I received the order, I got 20X30 X1. Of course I had to return those since they were too big-----and then I was charged for shipping, so there wasnt enough money to order the correct size. I ended up going to a local store and finding something that would work. I tried the order again (not ordering, just seeing if that would happen again) and when I clicked on a 4 pack or other bundle, sure enough, the size changed. So, just beware that could happen and check and check again to make sure you are ordering the right thing.

This product is about aa 1/4 inch to long and wide. Can still press in.

I got these before I knew 3M made MPR 2800 filters in 20x20x1. These dont do as good as a job with fine dust around the house as 2800s, but they are advertised at MPR1500 so no complaints. I am very happy with these 3M filters as I know that I am getting the filtration rating they advertised, unlike the cheaper no name brands. Yes they are pricier than other brands, but I wanted to make sure I received the filtration I needed for the house.

They are a little pricey, but you need them and they are way less then risking your furnace breaking. We have purchased several times and they do the job

The price is as good as Lowe’s and delivered to the front door with no extra charge. I change the filter very often and the AC works extra well. The money that I spent on filters I make it up on the electric I save.

I took measurements from my last filter I had (different brand) and matched it up to this one. I have a in the ceiling filtration system so my filter goes into a vent in the ceiling. I went to put this in and it is a VERY VERY tight fit, not at all like my previous filters. I was a bit displeased I had to scrunch it in, but it worked. I havent noticed any big changes in the air compared to my previous filters as of yet. Will update after pulling the filter out.

Item is just a little to big to fit in the opening, had to crush the sides to be able to install in my 14x14x1 air return.

Filter works great but doesnt fit properly. These are slightly too large and can be a pain to get situated.

Exactly what I ordered

Had to stabilize because it made a horrific thumping noise when the ac starts and stops. Not a good fit in the duct. Too expensive for that to happen.
